Extending Awareness Below the Waterline
Subvex is designed to act as the underwater intelligence layer of autonomous maritime missions. Combining deep-sea endurance, onboard AI processing and advanced subsea sensing, the platform enables persistent intelligence collection in complex underwater environments.
As part of the Quantum Systems Maritime Solution, Subvex contributes underwater awareness, environmental intelligence and sensor-derived insights to a common operational picture. Whether monitoring critical subsea infrastructure, supporting maritime surveillance missions or operating in denied environments, the platform extends visibility into areas where traditional systems face significant limitations. Integrated through MOSAIC UXS, Subvex transforms underwater sensor data into actionable intelligence for maritime decision-makers.
The Underwater Intelligence Network
While capable of operating independently, Subvex delivers its greatest operational value as part of a coordinated underwater intelligence network. Multiple Subvex systems can collaborate as an autonomous underwater mesh, distributing sensing tasks, sharing intelligence and extending coverage across vast maritime areas.
Working alongside Seavex mission hubs, Subvex benefits from a unique sustainment architecture. Seavex provides energy, communications and data services, enabling autonomous docking, battery recharging, secure data transfer and rapid mission redeployment without direct operator involvement. Integrated through MOSAIC UXS, this scalable system-of-systems approach enables continuous underwater intelligence gathering, from a single Seavex-Subvex pair to distributed fleets operating across the maritime domain.
One Platform. Multiple Underwater Missions.
Built on a modular autonomous platform, Subvex supports a wide range of underwater intelligence and surveillance missions. Advanced sonar systems, hydroacoustic sensing and onboard AI processing enable the platform to detect, classify and monitor activity across complex subsea environments. Whether protecting critical underwater infrastructure, monitoring sensitive maritime areas or contributing to distributed underwater awareness networks, Subvex provides persistent intelligence below the waterline while operating as part of the Quantum Systems Maritime Solution.
